Samesurf’s Patented Security Boundaries for Agentic AI

Samesurf is the inventor of modern co-browsing and a pioneer in the development of foundational systems for Agentic AI.

Digital workflows in modern enterprises are no longer confined to reactive systems or basic AI tools. The rise of Agentic AI marks a profound shift: technology can now perceive, reason, plan, and act autonomously to achieve complex objectives. Unlike traditional generative AI which simply retrieves or analyzes information, Agentic AI executes high-level tasks with precision, ultimately transforming how organizations handle operations like troubleshooting, secure transactions, and workflow correction.

This transformation, however, exposes enterprises to new risks. AI agents operate within non-deterministic models, which makes them vulnerable to sophisticated attacks such as prompt injection, remote code execution, and multi-step exploits that can compromise internal systems. Unlike conventional endpoints, a compromised agent can act as an internal threat by wielding privileged access and advanced planning capabilities. Traditional perimeter defenses are insufficient, as they cannot account for the dynamic, autonomous nature of these systems.

Addressing this challenge requires a foundational architectural solution. Samesurf’s patented cloud browser technology provides a secure, isolated execution environment for Agentic AI and ensures that the agent’s operations remain fully contained and auditable. By separating the computational core from external influences, Samesurf mitigates the risks associated with autonomous exploits while allowing the AI to operate with human-like dexterity across digital workflows. This architecture not only preserves operational continuity but also establishes a trusted framework for deploying autonomous agents in sensitive, high-stakes environments.

The New Cyber Vulnerability Landscape of Agentic Browsers

The deployment of Agentic AI on the open web exposes a fundamental paradox: the very capabilities that make these systems powerful, autonomy, perception, and action, also create novel and sophisticated attack surfaces. AI agents process natural language and interpret web interfaces in ways that leave them vulnerable to manipulation by malicious actors. Hidden instructions embedded in web pages or emails can coerce an agent into performing unintended actions, such as navigating to sensitive sites or exfiltrating private data. Similarly, manipulations of the user interface, including fake buttons or hidden elements, can mislead the agent’s reasoning and trigger unauthorized behavior. Persistent memory across sessions amplifies these risks, as poisoned or contaminated context from prior interactions can compromise future workflows, which leads to repeated data leaks or unintended actions. Because these agents operate within non-deterministic reasoning frameworks, traditional detection mechanisms are insufficient. Addressing these threats requires a deterministic, absolute architectural solution that ensures the AI’s execution environment is fully isolated and immune to contamination, transforming a volatile operational landscape into a secure, trustworthy foundation for autonomous action.

Samesurf’s Patented Architectural Defense

Samesurf provides the architectural foundation necessary to meet the strict security and accountability requirements of autonomous enterprise operations, particularly in regulated sectors such as finance and healthcare. Samesurf’s platform is built on a patented, server-driven architecture supported by intellectual property, including USPTO patents 12,101,361 and 12,088,647 which hold February 2023 priority dates. These patents define the operation of cloud browsers within synchronized browsing and Agentic AI systems, which cover the ability of autonomous AI-enabled devices to simulate human browsing, perceive their environment, and manage the sharing of navigational control. This patented foundation enforces security, auditability, and operational control at every layer, thereby addressing risks that cannot be mitigated by simple policy controls alone.

At the heart of Samesurf’s defense is Remote Browser Isolation. This methodology secures browsing activity, web scripts, and potentially malicious content by hosting all execution on an isolated cloud server. Relocating the environment away from the endpoint dramatically reduces the attack surface and prevents malware or rogue scripts from reaching enterprise devices or networks. The architecture creates a digital air gap that ensures sensitive data processing and autonomous agent activity remain fully isolated. The endpoint device receives only a passive, pixel-based stream of the rendered content while active, executable page content never touches the host environment. This separation transforms security from reactive patching into proactive neutralization, which ensures that even sophisticated web-based attacks, such as cross-site scripting, are contained entirely within the disposable cloud sandbox and cannot compromise the enterprise network.

The Disposable Execution Environment

The principle of disposability forms a second critical pillar of Samesurf’s security boundary to ensure that any temporary compromise or contamination is never persistent and that each autonomous workflow starts with a clean slate. The Samesurf Cloud Browser functions as a disposable execution environment, similar in structure to a container or CI/CD executor, spun up exclusively for a specific task and fully destroyed upon completion. This design inherently prevents memory persistence attacks.

Samesurf enforces strict data minimization principles, which guarantees that no session data is stored, written to disk, or retained beyond the active session. All information generated, processed, or perceived during an autonomous session is immediately disposed of at the conclusion of that session. This deterministic disposal mechanism acts as a fail-safe against the inherent ambiguity of non-deterministic AI threats. Since detecting LLM contamination through prompt injection is highly challenging, the architecture guarantees that any compromise remains strictly transient. By eliminating data persistence, Samesurf simplifies regulatory compliance, addresses challenges such as GDPR, and reduces the complexity of auditing, data lifecycle management, and deletion protocols.

The server-side execution environment incorporates robust containment and governance features. Sandboxing enforces strict resource limits on the agent’s computing activity, which helps mitigate risks such as tool abuse where an agent might attempt to invoke compromised APIs or automation tools. By operating entirely within a controlled cloud instance, the agent cannot access or invoke unsanctioned plugins from the host environment.

A key component of this containment is the provision of an instant kill switch. If an agent exhibits rogue behavior, potentially triggered by prompt injection or unauthorized navigation, the server-side environment can be terminated immediately, thus preventing a localized issue from escalating into a systemic breach. Samesurf also enforces the principle of least privilege, which constrains the agent’s operational scope through features such as single-tab browser sharing, ultimately preventing exposure of desktop files or unrelated browser tabs, even within the isolated cloud environment.

Protection of Agent Core Reasoning and Enterprise Data Exfiltration Defense

The ultimate protected assets are the agent’s core reasoning capabilities, including proprietary LLM logic, and the enterprise’s sensitive data. Samesurf’s architecture provides layered defense for both.

Server-side sandboxing ensures that the agent’s core LLM logic, proprietary algorithms, and internal state instructions are fully separated and digitally shielded from the volatility of active web content. This architectural separation prevents critical web context leakage. In client-side environments, back-end instructions and system details are fully exposed and can be exploited by threat actors who compromise the browsing session. Samesurf’s air gap ensures these internal mechanisms are never exposed.

The agent’s operational identity, including API keys and access tokens, is also protected. Samesurf’s Remote Browser Isolation architecture protects credentials in use during web interactions. This prevents active capture or misuse by compromised content and maintains the integrity of the agent’s operational scope.

Samesurf leverages its foundational patents to integrate robust Data Loss Prevention controls directly into the execution environment. The platform implements dynamic redaction by automatically scrubbing sensitive elements such as passwords, personally identifiable information, and credit card numbers during active sessions. This elevates redaction from a privacy feature to a core security control. Even if a malicious prompt attempts to instruct the agent to capture sensitive data, dynamic redaction prevents exposure and safeguards information while the agent operates autonomously or under human supervision. The system also enforces explicit input blocking, which provides fine-grained control over sensitive data handling.

Server-side execution ensures zero interaction between a compromised agent and the local host environment. By relocating execution to the isolated cloud sandbox, the architecture blocks the agent from accessing the host operating system, applications, system trays, or network connections. This containment prevents lateral attacks and neutralizes sophisticated privilege escalation attempts and data exfiltration routes that occur in client-side deployments. Secure pixel streaming and architectural separation create a resilient security trust layer to ensure the enterprise network and endpoints remain fully protected from autonomous agent risks.

Governance, Traceability, and Regulatory Compliance

Enterprise deployment of agentic AI demands demonstrable accountability and auditable operations, particularly in regulated industries. Samesurf provides the essential governance framework to meet these requirements.

Samesurf’s platform centralizes control over the agent’s full operational lifecycle by enforcing security, auditability, and operational oversight. By routing all autonomous web interactions through a secured, governed, and fully logged server-side environment, enterprises gain complete visibility into all AI agents. This approach prevents unmanaged or “shadow AI” deployments and ensures that all agent activity is inherently monitored and controlled.

Samesurf captures detailed logs of the agent’s internal states, prompts, actions, and decision processes. This high-fidelity audit trail converts abstract governance principles such as accountability and explainability into verifiable and enforceable security outcomes.

The system also supports real-time supervision and Human-in-the-Loop intervention. Human oversight is fully integrated without compromising the security boundary, which allows instant intervention while sensitive data remains isolated and protected through dynamic redaction.

Samesurf’s architecture provides the structural foundation for achieving and demonstrating regulatory compliance in complex, cross-jurisdictional environments. GDPR and data confinement requirements are addressed through instant session disposal and strict regional data controls, which reduce risks of unauthorized processing and simplify compliance. The combination of architectural isolation, immediate data disposal, and fine-grained access controls ensures SOC 2 Trust Services criteria are met. Dynamic redaction and enforced isolation further protect personally identifiable information and sensitive health data, which empowers AI agents to safely operate under HIPAA regulations. By embedding trust at the core of autonomous enterprise operations, Samesurf enables organizations to safely leverage AI while meeting the most stringent regulatory standards.

Establishing Operational Trust for Enterprise-Scale Autonomy

The deployment of Agentic AI marks a transformative shift in enterprise automation, as it offers unprecedented efficiency while simultaneously amplifying cyber risk. AI-enabled agents must interact with the volatile, untrusted public web using tools and permissions that, if compromised, could threaten the integrity of the entire enterprise network.

Client-side execution is insufficient for enterprise-scale autonomy, as it collapses security boundaries and allows lateral privilege escalation in the event of a compromise. The solution lies in establishing a perimeter defined by architectural isolation rather than network configuration.

Samesurf’s patented Cloud Browser delivers this critical foundation. Through Remote Browser Isolation, all active web content is hosted and executed within a server-side, disposable environment. Malicious scripts and rogue content are contained harmlessly within the ephemeral cloud sandbox, while only passive pixel streams reach the agent’s core environment. This digital air gap ensures complete operational separation by protecting both the agent’s reasoning capabilities and the broader enterprise network from external threats.

The architecture also incorporates a robust security trust layer with patented governance features, including dynamic redaction and immediate session disposal. These measures allow organizations to deploy Agentic AI at scale with confidence, thereby ensuring secure, auditable, and compliant operations in even the most highly regulated environments.
